The system includes a converter operatively connected to an alternating current (AC) power source and a direct current (DC) bus, an inverter operatively connected to the motor and the DC bus, and a hybrid DC link system operatively connected between a high side and a low side of the DC bus. The converter includes a first plurality of switching devices in selective communication with each phase of the AC power source and the DC bus. The inverter includes a second plurality of switching devices in selective communication with each phase of the motor and the DC bus. The hybrid DC link system includes a ripple current control branch in parallel with the energy buffer branch.

    系统包括操作性地连接到交流(AC)电源和直流(DC)总线的转换器、操作性地连接到马达和DC总线的逆变器和操作性地连接在DC总线的高侧和低侧之间的混合DC链路系统。转换器包括与AC电源的每个相和DC总线选择性地连通的第一多个开关装置。逆变器包括与马达的每个相和DC总线选择性地连通的第二多个开关装置。混合DC链路系统包括与能量缓冲分支并联的纹波电流控制分支。
